Key Features and Benefits

1. Thirteen-Pin Female Electrical Interface

The MCILRA13F features thirteen female electrical contact positions in a compact circular connector interface.Its thirteen-pin configuration supports multiple electrical circuits through a single connector assembly, helping simplify wiring arrangements in underwater equipment.Depending on the approved pin assignment, the contacts can be allocated to suitable applications involving:

• Marine sensor signals
• Instrumentation and measurement circuits
• Auxiliary electrical power
• Subsea control systems
• Environmental monitoring equipment
• Underwater data acquisition
• ROV and AUV instrumentation
• Multi-channel electrical interfaces

Using one thirteen-pin connector can reduce the number of individual connectors required in some equipment designs.The actual allocation of power, signal, and control circuits must be established using the approved wiring diagram. Contact count alone does not establish compatibility with a particular communication protocol.

2. L-Shaped Right-Angle Cable Exit

The defining feature of the MCILRA13F is its right-angle cable configuration.Unlike a conventional straight inline connector, the L-shaped body directs the cable away from the side of the connector mating interface.This can provide several practical advantages:

• Reduced straight-line clearance requirements
• More controlled cable routing
• Improved integration in compact housings
• Less interference with adjacent components
• Greater flexibility when planning cable paths
• A cleaner layout in tightly packed equipment

The right-angle configuration is particularly useful when a straight cable exit would interfere with a housing wall, mounting bracket, nearby connector, or other mechanical component.Before finalizing an equipment design, verify the actual connector envelope, cable exit direction, and minimum cable bending radius against the approved mechanical drawing.

3. Rated Voltage of 550V AC/DC

The HYSF Micro 10–16 Pin connector series specifies a rated voltage of 550V AC/DC.The MCILRA13F can be considered for electrical systems operating within the approved rating of the selected connector and cable assembly.For multi-channel applications, engineers should evaluate the voltage requirements of individual circuits and the insulation requirements of the complete assembly.Important considerations include:

• Maximum operating voltage
• Differences in potential between adjacent circuits
• Cable insulation rating
• Conductor separation
• Grounding arrangements
• Operating temperature
• Electrical protection requirements

The applicable operating voltage must be confirmed for the actual product configuration. The series voltage rating should not be interpreted as approval for every possible combination of voltage, current, and environmental conditions.

4. Rated Current of 5A

The Micro 10–16 Pin series has a catalog rated current of 5A.This rating is relevant when selecting the MCILRA13F for applications involving multiple low-power circuits, instrumentation, and suitable auxiliary electrical connections.The permissible current depends on the approved connector design and operating conditions.When evaluating a complete cable assembly, consider:

• Current through each contact
• Number of simultaneously energized contacts
• Conductor cross-sectional area
• Cable temperature rating
• Heat dissipation
• Voltage drop
• Contact resistance
• Continuous versus intermittent loading

For equipment operating continuously near its electrical limits, the complete connector and cable assembly should be evaluated under the intended operating conditions.

• Compatibility with compact underwater equipment layouts

The connector should be inspected periodically for cuts, cracks, deformation, or other visible signs of damage.

7. Gold-Plated Electrical Contacts

The MCILRA13F product listing specifies gold-plated electrical contacts.Gold plating provides a conductive mating surface and helps reduce oxidation at the contact interface.Reliable electrical contact is important for underwater instrumentation, where a connector may carry multiple independent circuits.To maintain connector performance, the mating interface should be kept clean and handled according to the applicable installation instructions.Contact numbering and conductor identification must be verified against the approved wiring diagram before the connector is integrated into a system.

8. Standard One-Meter Cable

The standard MCILRA13F inline configuration is listed with an approximately 1-meter cable.This cable length provides a convenient starting point for many compact subsea instruments and equipment assemblies.Customized cable lengths can be specified when the standard length does not match the installation requirements.Possible customization considerations include:

• Alternative cable lengths
• Cable jacket selection
• Conductor specifications
• Wiring identification
• Cable routing requirements
• Termination arrangements
• Integration with existing equipment

The final cable specification should be agreed upon before production.When using the right-angle configuration, the cable routing path and bending radius should be considered together with the connector body dimensions.

9. Compact Installation for Space-Constrained Equipment

The MCILRA13F is designed for equipment where conventional straight inline connectors may require excessive clearance.Its L-shaped configuration can help accommodate cable routing near equipment walls or within compact mechanical assemblies.Potential applications include compact ROV tool interfaces, AUV electronics modules, underwater sensor housings, and marine research equipment.The right-angle design can simplify cable routing, but the available clearance must still be checked against the connector’s actual dimensions and cable exit direction.The final installation drawing should be used to verify the complete connector envelope.

10. Wet-Mateable Micro Circular Design

The HYSF Micro Circular family is designed for underwater mating applications.The MCILRA13F can be considered for systems requiring detachable electrical connections, provided the exact configuration and mating interface are qualified for the intended environment.Applications may include removable sensors, underwater instrumentation, modular ROV components, and marine equipment requiring cable replacement.Wet-mateable capability does not automatically mean live-mateable operation. Electrical power should be isolated before mating or unmating unless the complete assembly has been specifically qualified for energized operation.

11. Customization for OEM and Subsea Projects

Different underwater systems may require different cable lengths, conductor arrangements, mechanical clearances, or electrical ratings.The MCILRA13F product family supports customization of cable length, interface specifications, and electrical configuration according to project requirements.For OEM integration, engineers should define the following before ordering:

• Required pin count
• Female contact configuration
• Cable length
• Cable jacket material
• Electrical rating
• Mating connector model
• Required pressure capability
• Cable exit direction
• Mechanical installation clearance
• Wiring and conductor identification

Confirming these details in advance helps reduce the risk of mechanical interference or incorrect electrical integration.
